These are photos of oil leaking from my hydraulic motor or hst motor. I'm no mechanic but and this is my first skid steer. It looks like its coming from a gap in the housing, would there be a seal in there thats blown or something? It started happening today while on a job. It leaks when the machine is on, stops when it is off. It has a fairly steady drip so I need to get it fixed. I'm looking for suggestions on what it could be, and what could have caused it and what can fix it. Thanks, Nick
I'm talking in general just because I don't exactly what you are working on. I'm think the bolts holding the motor together are lose and the oring between section blew out.
Thanks Bobcatdan, so I'm guessing its not just a case of tightening the bolts? how many hours should it take to replace the oring? Its a toyota 4sdk8 btw
Nick009, If you don't have any hydraulic repair experience, it will be best to remove the motor & take it to a repair shop & let them do it - should only take an hour, if they have the parts/ seal kit. When you undo the hoses - make sure every thing is clean - don't let any dirt enter the system. It may leak oil from the smaller drain hose, so caps & plugs would be required to stop the oil effectively.
Thanks airman I've taken the whole machine in to get it fixed. I told the guy what was wrong and he quoted me 3 hours @100/hr plus $120 for the seal kit. Does that sound about right? Would it take a professional an hour to get the thing in and another hour to get it out?
Not very familiar with a toyota - but if its anywhere close to a Bobcat, 3 hours is correct maybe a little more if things dont cooperate. Skid steers are normally a pain to work on, especially the hydraulics , they are in the worst area to get to. The price per hour and kit are close - shop work here is around $ 120 per. hr. The majority of all leaks on these are o-rings , sometimes you can get by with just tightening if it didnt come too loose and cut the o-ring.
Damn I wish I'd tried tightening it first!! I'm picking it up this morning so I'll make sure the other side is tight before I put the bottom plates back on.
Hi nick009 How did you go with this 10 years ago ? Have exact same problem, only 2000hrs on the machine first problem I have had with it. Cheers
Hi Nick, I have just found the same problem with my for sdk8 what did you do to fix it, cheers
